To all zul/Nitrit may concer/t:

Be it known that l, GUUL O. BR.,A GER, a citi- Zen of the United States, residing at Osage, in the county of Mitchell and State ot' Iowa, have invented a new and useful Pocket Cash-Register, of which the following is a specification.

My invention relates to cash-registers, and particularly to a compact device ot simple construction which is adapten to be carried in the pocket forrepeated consultation in adding separate sums or in registering the amounts of successive payment-s or receipts and similar purposes.

Further objects and advantages of this invention will appear in the following` description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a register constructed in accordance with my invention. Fig. 2 is a front view with the face-plate omitted. Fig. 23 is a ccntral transverse section. Fig. 4 is a transverse section on the line 4 it of Fig. 2.

Similar numerals of reference indicate corresponding parts in all the gures of the drawings.

1 designates a casing having its face-plate provided with indicating-openings 2 and 8, through which are exposed, one at a time, the characters, as numerals, of the operating units and tens disks 4C and 5; units and tens result-openings 6 and 7, through which are adapted to be exposed the characters, as numerals, of the units and tens result-disks S and 9, and a hundreds result-opening 10, through which are adapted to be exposed the characters, as numerals, oi the hundreds result-disk 411.

The operating or indicating disks are mounted upon arbors 12 and are provided with handles or finger-pieces 13 and la, rcspectively, which project through slots 15, formed in the ends of the casing, said ends being concentric, respectively, with the arbors of the disks whose handles or operatingpieces extend therethrough, and in order to facilitate the movement of the operating or indicating disks said handles or Enger-pieces are preferably provided with pencil openings or perforations 1G. The peripheries o'f the convexed or rounded end portions of the casing are provided with characters, as numerals, corresponding with those of the operating or indicating disks to facilitate the turning ol' said disks through the desired arc to bring a numeral corresponding with the amount to be registered into view through the indicatingopening which cooperates therewith.

Each operating or indicating disk is connected by ratchetincchanism consisting, for instance, of a ratchet-wheel 17 and a springactuated pawl 1S, to a spurred wheel or gear 19, which is fixed to and carried by the coaxial result-disk, whereby when the operating or indicating disk is turned in one direction a corresponding motion in the same direction is communicated to the result-disk to bring a suitable character of the result-disk into view through the cooperating resultopening, whereas when the operating or indicating disk is turned in the opposite direction it will rotate independently of the result-disk to allow said operating or indicating disk to be returned to its initial position with the initial character, as Zero, of its scale exposed through the indicating-opening.

When the apparatus is designed for registerin g expenditures, receipts, or other amounts wherein the decimal system is employed, each operating and result disk is provided with one or more sets of ten numerals, and in order to provide for the communication or carrying over of tens from the units resultdisk to the tens result-disk when an amount corresponding with ten units has been registered upon the former the units-disk is provided with a stud 20 to engage the spurs of the gear 19, carried by the tens result-disk, and in order to allow free rotation of the result-disks of higher denomination said studs are preferably pivotal, as shown, and are held in operative position by means of actuating'- springs 21. In order to prevent excessive rotation and looseness of the result-disks, holding-springs 22 are arranged in operative relation with said gears 19.

The hundreds result-disk is provided with a gear 23, held from accidental rotation by means of a spring 2i and adapted to be engaged by a pivotal spring-actuated stud 25, carried by the gear ot the tens-disk, the con- IOO e tenes? struction and operation of this stud being similar to that described in connection with the stud carried by the units result-disk, whereby after the turning of the tens-disk through a distance necessary to register ten tens a forward step is imparted to the hundreds-disk to register one hundred. The hundreds-disk is preferably provided with a screw-head 2G, or its equivalent, which projects through an opening in the face-plate ot the casing, whereby said disk may be turned to Zero.

rlhe mechanism above described is preferably duplicated upon the opposite side ot" the casing, as indicated in Fig. 2, whereby the mechanism upon one side is adapted for registering cents and dollars, While the mechanism. upon the opposite side is designed for registering dollars and hundreds ot' dollars, but it is obvious that the utility of the device is not limited to registering money receipts or ezipenditures. The same may be employed to register the points et a card or other game and `t'or other analogous purposes.

Various changes in the form, proportion, and the minor details ot' construction may bc resorted to without departing from the spirit or sacrificing any oi the advantages of this invention.

IIaving described my invention, what I claim is l. A registering device having a casing, units, tens and hundreds result-disks, means for communicating motion from one disk to the next of higher denomination, operating er indicating disks mounted coaxially with the units and tens disks, respectively, ratchet connections between the operating or indicating and the contiguous result-disks, and handles or finger-pieces on the operating or indicating disks extending through concentric slots in the contiguous Wall of the casing and adapted to be actuated independently, substantially as speci lied.

2. A registering device having units, tens, and hundreds result-disks, gears carried respectively by said disks, retaining-springs in engagement with the teeth o'll said gears to prevent accidental rotation, spring-actuated pivotal lugs carried by the units and tens disks 'for communicating motion from one disk to the next oi higher denomination, exposed means carried by the hundreds-disks for turning the sameindependently ot the eooperating disks, operating or indicating disks mounted coaxially with the units and tens disks and provided with handles or fingerpieces having terminal perlorations, and a casing inclosing said disks and provided with indicating and result openings i'or exposing, respectively, the characters on the operating and result disks, substantially as specified.

A registering device having a casing,

units, tens and hundreds result-disks, means for communicating motion 'from one disk to the next of higher denomination, operating or indicating disks mounted coaxially, respectively, with the u nits and tens disks, ratchet connections between the operating or indicating and contiguous result-disks, and exposed means for comnninicating motion to each of the opera-ting or indicating disks and the hundreds result-disk, whereby either of said disks may be actuated independently to register an amount aggregating tens or hundreds, substantially as specified.

In testimony that I claim the foregoing as my o\vn I have hereto ailixed my signature in the presence of tv'o Witnesses.
